How to choose the appropriate grease for the ratchet mechanism?

The grade of the grease applied in the ratchet and pawl area, must have an NLGI rating of 00, 0, or 1. Do not use oils with tackifying additives, such as Phil’s Tenacious Oil®, as these can gum up the mechanism and cause the pawls to stick.

Why do you choose external nipples for the rim?

When adjusting the spoke tension or truing the wheel, you do not need to remove the tire, tube and rim strap.

It is adjustable from both sides of the nipple, either by using the standard nipple driver or from the inside using the inverted straight nipple driver.
